The media often point an accusatory finger at new technologies; they suggest that there is always a loss of information or quality, or even that computer-mediated communication is destroying language. Most linguists, on the contrary, are firmly convinced that it is better to consider language as an evolving and changing entity. From this point of view, language is a social tool that has to be studied in-depth through the prism of objectivity, as a process in motion which is influenced by new social and technological stakes, rather than as a fading organism. In this volume we study and describe the societal phenomenon of SMS writing in its full complexity. The aim of this volume is threefold: to present recent linguistic research in the field of SMS communication; to inform the reader about existing large SMS corpora and processing tools and, finally, to display the many linguistic aspects that can be studied via a corpus of text messages.<br />These articles were previously published in <i>Lingvisticae Investigationes</i> Vol. 35:2 (2012).
